Reynolds' shoulder surgery is a huge blow. Sinkbeil looks like a non-prospect. Parmelee's a DH in the field who doesn't hit well.
Yet the worst of the crop looks to be Drabek. His stuff wasn't very good from the moment he got drafted (no juice = no stuff?) and now he's injured. He might have to shift to 2B sooner rather than later. Plus, he came into last year's draft with an enormous Milo slapped on his head.
I'd say Stubbs has only been the fifth most disappointing debut. Hochevar's been pretty bad too (despite the major league toe dip). Lincoln's surgery and Jeffress' suspension (chronic?) are definitive setbacks. I also still like Stubbs better than Colvin, who played better at higher levels, but is devoid of OB skills.
